Comparison of parameters of solar power plants with same characteristics installed in four different directions

In this thesis, the electrical calculations of four 1 MW Solar Power Plants (SPPs) located in four different directions, established in Samsun, were analyzed and compared in terms of various parameters. The daily production data of the plants for the years 2021 and 2022 were used in the thesis. In this way, a comprehensive data source was obtained for four different directions. Values such as temperature, relative humidity, wind speed, panel direction, panel angle and pollution taken from the power plants are the values taken in daily and monthly periods. It has been observed that the factors affecting the production values in the months when the irradiance values decreased were climatic effects. In cases where the main factor is the lack of radiation, the angle of incidence of the sun to the earth started to decrease on September 23 and started to rise on March 21. The situation recorded between these dates is that the production differences between the West and the East did not show any variation. Production differences varied between 30 and 55% between the North and South directions. The most obvious months of the difference are December and January, when the sun's rays are most oblique to the northern hemisphere. The feasibility study of the installation of SPPs for the Black Sea climate according to different roof aspects was also carried out prospectively, and the responses to possible natural events were reported as recommendations.
